2015 formats to be revealed before Sandown

V8 Supercars is set to reveal details of the 2015 calendar and race formats before the next event, the Wilson Security Sandown 500, beginning September 12.

At the Sydney Motorsport Park 400 over the weekend, the V8 Supercars only ran on Saturday and Sunday, raising the question of the future of Fridays at race events.

And with testing rules also on the agenda - why not combine the two?

Teams are currently allocated three independent test days a year at their local circuit, as well as the compulsory pre-season test day involving all cars, held at Sydney Motorsport Park for the past two years.

V8 Supercars CEO James Warburton believed incorporating testing into a Friday race meeting ensured maximum exposure for teams, and more opportunities for fans to see and get an insight into the sport.

"Teams could be testing at a whole range of tracks they don't test at, so it's not just Winton and Queensland Raceway. It's actually about how testing comes into the entire format," Warburton said.

"The types of exciting places they can test at, where they can learn some new things as well.

"That's all up in the air, but we'll announce a decision just before Sandown, so obviously we've got the calendar and the formats to announce."

Warburton and the V8 Supercars Commission are mindful however that a combined approach may need to be taken to testing.

"I wouldn't call it a testing ban - I'd talk about testing coming into the racing arena, so really loyal fans can actually see activities on a Friday," he explained.

"I think things like that are good, as long as it doesn't interfere with what teams need to do, quite significantly from a test point of view.

"They still need to continue to test privately, so it's a combination. So we're looking at a range of things."

There's still plenty of news to come relative to V8 Supercars in 2015, with more details of the media deal to emerge through Channel 10 and FOX Sports.

"The ability to do more on Friday and get full coverage throughout the week is going to be a real benefit to teams and to sponsors - their sponsors, our sponsors. I think things like that will roll out."

Most teams are set to test next week prior to the Pirtek Enduro Cup, prioritising co-driver miles before the long-distance races, with some teams racing the clock after extensive damage over the weekend in Sydney.

"There's lots of discussion at a Commission level because we also have a lot of test days that are at tracks with no one, as opposed to being able to bring some of the testing into events.

"So again, from a cost point of view, it will save the teams some money, not having to hire the facilities, things like that.

"There are lots of different models we can look at."

Warburton recently said most of the the Championship events were locked infor several years on the calendar, with a key focus on Australian rounds for an Australian Championship.
